.To all whom t may concern: v

Be it known that I, WILLIAM P. lemen, a citizen of the UnitedStates, and resident of New York city, county and State of' New York, have invented an Improvement in Brick' Lifting and Transferring Mechanisms, of which the following description,

the handling of Ygreen bricks in the process 'of manufacture, either in closecr'open for mation. When used for handling burned 2o" brickscn 4maar@ as for delivery to the point of destination for use, the apparatus is also adapted to ,Serve as a means'of counting the bricks as it comprises a cage, which, when filled either completely or to a definite extent, will hold a vdenite ,number of bricks.

Tlieinvention consists in a liftingframe which is preferably, though not necessarily, in the :form of an inclosing cage adapted to be set down over Athestack of bricks to be lifted, and in combinationtherewith a set of lifting rods or bars to be raised by .said frame adapted to yengage underneath the stack v)for lifting the same, and having provision .to laterally ,engage and frictionally grip the lower-most layer of bricks in thev stack, which, for -this purpose, is arranged in spaced apart lines, the spacesbetween the lines serving for the introduction of the liftin'bars.

he invention will be more fully ,understood from the following detailed description taken in connection ,with the accom- -pazziying drawings, and is hereafter set 'forth in the appendedclaims.

Referring to the drawings: Figure l is a -vertical section through the ap aratus in a direction lengthwise of the bars and lslnowingone of said bars in elevation. Fig.

2 'is a fragmentary detail end elevation lookingtrom the left in Fig. l. Fig. Sis a fragmentary horizontal sectional View through one of the litin bars. Fig. 4: is a fragmentary velevation s owing a portion ottone of f bars 5 is a plan of one of .the li the lifting bars removed, a line of bricks being shown in ldotted lines to illustrate the manner of rippin the same, and' Fig. 6 is an enlarge detai end elevation further showing the nuannerv of frictionally grippir'g the 'bricks of the bottom lines.

' rhe framework 10 may be of any suitable construction and is preferably :formed as a rectangular openwork cage having top horizontal bars 11 to vwhich lifting straps 12 may be xed. The cage shown has a series of vertical bars or plates 13 fixed to thetop horizo1,1,fit1'bars l1 and these may be suitably secured together Aat their bottoms by other` vvhorizontal bars 14:, the whole constituting the rectangular sides of a cage open at its bottoni and preferably of a size to t a stack composed ci some denite number of bricks in a predetermined stacked form. Along two opposite sides of the cage so forme near its bottom are Xed clips 15, 16, the clip 15 having an inturned led-ge 17 inclined slightly upward and the clip 16 at theopposite side having a ,similar slightly upturned ledge v18-`j1 rojecting outward therefrom.

These ledges are `for the purpose of receiving ,and holding the ends of a Aset of lifting bars 19, ,these bars .having at their forward ends slightly downturned projections 20 adaptedlto interengage with the ledge 17 and at heir rearends br ckets 21 with lnturned en s which may be s 'ghtly bent downward to securelyinterlock 'with the upwardly bentI ledges 1,8. The several lifting bars are similar in construction and each consists of two be .membrs2s2, 2.3, preferably of wel@ anshown as Lfshaped in cross section and hed in parallelism or Aslightly converlgi toward their outer ends andwiththeir inner vertical sides spaced apart approximately the .width of a brick 0r' .a little farther and :held in this relation by being at their rear ends to a stiff' strong plate 2t which may be a 'part .of the bracket 21. The bar members 22, 12.3 are so xcd 'to the .platelet that-.their horizontal ilanges 25, 26 extend .oppositiely outward at the top of the lifting ,bar Structure ,thus formed. A. suitable handle QTmay be -Xed-to each lifting bar atits rear-end, being as shown, suitably 51nd to ethe ,plate 24C. The inner ,vertical sides or flanges' ,Off the bar elements 22, 23 ,have a serieso Slots 28 formed therein at fredt i intervals, in practice about three. inches While the apparatus has beendescrlbed as for the handling ofzbricks, it is to be understood that this vparticular application of the invention is merely -fillustra'tive and that the mechanism is likewise adapt/ed for handling other kinds of merchandise or material composed of articles lof denite form adapted A to be arranged 4in etackedpiles.- I therefore desire tocover` the apparatus for luse in handling such material gemrally.l
